Title: Improvements relating to means for feeding bottles to a bottle conditioning plant
IPC: B08B9/44
Filed: 1953-08-07
Abstract: 744,334. Endless chain conveyers. LIQUID CARBONIC CO., Ltd. Aug. 7, 1953 [Aug. 22, 1952], No. 21831/53. Class 78 (1). Bottles are fed to a washing- or other conditioning-machine by a continuously moving elevator having longitudinally and laterally spaced lifting fingers each engaging an individual bottle in a guide channel adapted to confine the bottle laterally on all sides, whereby successive groups of bottles are elevated. As shown, the fingers 64 have stems 63 passing through slots in the guides 53 forming the channels 52 and are carried by cross bars 58 extended between endless roller chains 38 running on guides 42, 43. To enable height adjustment of the elevator the lower chain sprockets 36 are mounted on a shaft 44 carried in bearing blocks 46 slidable between flanges 49 of a frame 47 which is slotted to receive the shaft. The elevator framework incorporates a detachable part which can be replaced by another of different length by which frame 47 can be connected to the frames of different washing machines. The angle of the elevator is also adjustable by varying the longitudinal separation of these frames. The bottles are fed to the channels 52 by an endless belt 19 running between side plates 33 associated with frame 47, oscillating guides 31 directing the bottles into rows aligned with the channels. The upper ends of the channels are continued by open curved channels 76 having slots 78 for the fingers. A widening of each slot near its remote end allows the fingers to pass through while eccentrically mounted pairs of blades 81 on a rotating bar 82 engage the bottle, one blade of each pair partially pushing a bottle into a holder 11 on the conveyer 10 of the washing-machine, while the other blade completes this movement. Driving gear. Stop mechanism.-The drive sprockets 37 of the elevator, and the rotating bar 82 are driven through separate clutches 102, 92 and 111, 112 from a shaft 94 in turn driven by a sprocket chain 118 from the washing- machine. Each driving plate 102 or 111 of the clutches transmits power to the driven plate 92 or 112 through balls 108 each engaging in a cylindrical recess in one plate and a conical recess in the other such that if the elevator is jammed the balls ride out of the conical recesses and force the driving plate away from the driven plate, freeing the clutch and simultaneously operating a micro-switch 109 or 115 adapted to cut off the driving motor of the washing- machine. Specification 703,229 is referred to.

Title: Improvements in or relating to cellulose derivative and process of preparation
IPC: C08B11/08
Filed: 1951-09-18
Abstract: Crude hydroxyethyl cellulose, containing not more than 1.4 hydroxyethyl groups per anhydroglucose unit, is washed with a non-alkaline aqueous medium, containing at least 20 per cent. by weight of water, to an ash content of less than 0.2 per cent. by weight, the water is then displaced by an inert, volatile, water-miscible, organic solvent containing not more than 15 per cent. by weight of water, the organic solvent is then removed and the product is acetylated to give a relatively undergraded hydroxyethyl cellulose acetate.  The washing medium may be pure water or a mixture containing at least 20 per cent. of water with a water-miscible organic compound, such as methyl, ethyl, propyl or isopropyl alcohol, acetone, dioxane, or formic, acetic, propionic or oxalic acid.  The displacing organic solvent may be anhydrous methanol, ethanol, propanol, isopropanol, acetone or dioxane, and mixtures of these with up to 15 per cent. of water, such as the azeotropic mixtures of ethyl alcohol and water or isopropanol and water.  The volatile organic solvent may be removed by drying in vacuo at 70 DEG C. overnight. Alkali, which is present in hydroxyethyl cellulose formed by hydroxyethylation of cellulose in the presence of alkali, is preferably neutralized prior to the washing step.  Suitable acids for this purpose include hydrochloric, nitric, formic and acetic acids and carbon dioxide.  The purified hydroxyethyl cellulose is acetylated in known manner, e.g. by pre-treatment with acetic acid followed by treatment in methylene chloride with acetic anhydride in the presence of perchloric acid and aqueous zinc chloride solution. The hydroxyethyl cellulose acetate produced has an intrinsic viscosity in acetone of at least 0.8 and preferably at least 1.5. The product may be partially hydrolysed to one containing at least 2.45 acetyl groups per anhydroglucose unit, such a product being particularly useful in plastics.  For other purposes, e.g. films, a product containing at least 2.85 and preferably 2.9 acetyl groups per anhydroglucose unit is desirable; in this case 0.3 to 0.6 hydroxyethyl groups per anhydroglucose unit may be present.

Title: Radio direction-finding
Inventor: ROBINSON STEPHEN JOSEPH
IPC: G01S3/06
Filed: 1967-05-15
Abstract: 1,126,290. Radio direction finding. MULLARD Ltd. 15 May, 1967, No. 22538/67. Heading H4D. The Specification describes a radio direction finder of the type having two orthogonally positioned " figure-of-eight " loop aerials SL and BL mounted on a rotatable assembly S/B and a fixed omnidirectional aerial V. By adding the output of aerial V, after phase quadrature shifting at Z, to the outputs of aerials SL and BL by means of windings SC and BS, switch FV under the control of pulses V1 switching the added outputs between inphase and antiphase conditions, four mutually orthogonal cardioids SN, SS, BW, BE are produced. Thus, if, with the cardioids aligned as shown, the bearing of the incoming radio signal is +30 degrees then the bearing cardioids BE and BW give responses E2 and E3 respectively. These responses are sampled by gated amplifier AB by means of gating pulses BE and BW, Fig. 5, and a signal indicating (E2-E3) appears across indicator BI. Such a signal is ambiguous, representing (180-30 degrees) as well as 30 degrees. To remove the ambiguity, responses E4 and E5 are sampled in amplifier AS from the sense cardioids SN and SS and on determining from the resultant difference signal across indicator SI, that E4 >E5 it is evident that the bearing is 30 degrees. The aerial assembly can then be rotated until E2=E3=E1 to a position giving the bearing.

Title: Improvements in and relating to alternating current track signalling
IPC: B61L1/18
Filed: 1921-08-30
Abstract: 186,239. Peter, L. H., and Westing- house Brake & Saxby Signal Co., Ltd. Aug. 30, 1921. Electrical systems, automatic.-In an alternating current signalling system the relays have two coils, one 4 connected to the track circuit 1 and the other 3 connected to the leads 5 of the signal circuit. The leads 5 are connected through a condenser 9 to the coil 8 of a transformer, the other coil 6 of which is connected across the track rails at the opposite end of the section from the relay winding 4. The winding 4 is short-circuited by a train on the section, leaving the winding 3 to operate the relay. According to the construction of the relay the, normal current in the winding 4 is in phase with the current in the winding 3, or is in quadrature with it, and to secure this the phase of the current in the winding 4 is adjusted by varying the capacity of the condenser 9 or by varying the transformer inductance by means of an adjustable leakage path for the flux, by movable windings, or by tappings. In general, the power-factor of the circuit is not unity and resonance does not occur, but in some cases the track circuits as a whole may be in a resonant condition, while the currents in the relay windings have a power factor considerably different from unity.
